Calculating your shutter speed when using Strobe mode - When in Strobe mode, your
cameras shutter will need to remain open long enough to capture all of the flashes. The
formula below will help you calculate the required shutter speed.
Number of flashes / Flash frequency = Shutter speed
Example: number of flashes @ 20 / flash frequency @ 5 (Hz), then the shutter speed = 4
seconds.
Further information:
• In Strobe mode only 1/4 flash power or lower can be selected. Full or 1/2 power cannot be
selected.
• To prevent overheating and component deterioration, do not use Strobe mode
repetitively in excess of 10 times. If Strobe mode is used in excess of 10 bursts the XMT
may automatically disable all flash modes to allow the components to cool down. If all
flash modes are disabled due to excessive Strobe bursts allow at least 15-20 minutes
for the unit to cool sufficiently.
